Very interesting project. I would like to build this power supply too.However I feel it need to be explained a bit more in detail especialy how to wind the transformer.
This is the most complicated and crucial part of this supply.

Hi all !
Very interesting topic, so please help me!?
I need a SMPS supply 2x35V/5A (project) for the audio amplifier with TDA7294/4om.
Give the suggestion that the power to choose!
thanks and cheers !!

may be you can try this, it works great. I have modified this design for +-70 and tested on a 400watts amp whihout much heating. You may be required to decrease the no. turns and gauge according to your requirement

Why modified this design for + /-70V, i need + /-35V for an amplifier with TDA7294!?
Question: Does this can be fed to drive amplifier with TDA7294?
thanks
